Driver information system
On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢• in the
instrument cluster is part of the On-Board Diag­
nostic (OBD II) system.
The warning/indicator light i lluminates when the
ignition is switched on and goes out after the en­
gine starts and the idle has stabilized. This indi­
cates that the MIL is working properly.
If the light does not go out after the engine is
started, or illuminates while you are driving, a malfunction may exist in the engine system. If
the light illuminates, the catalytic converter
could be damaged.
Continue driving
with reduced power (avoiding
sustained high speeds and/or rapid acce lerations)
and have the condition corrected. Contact your
authorized Audi dealer.
I f the light illuminates, the electronic speed lim­
iter may also be malfunctioning. For more infor­
mation
c::> page 28, Electronic speed limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
c::> page 192.
On-Board Diagnostics
Fig. 16 Loca tion of Data Link Connec tor (DLC)
On-Board Diagnostics monito rs the components
of your emission control system. Each monitored
component in your engine system has been as­
signed a code. In case of a malfunction, the com­
ponent will be identified and the fault stored as a
code in the control module memory .
28
The MIL light may also illuminate if there is a
l eak in the on-board fuel vapor recovery system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel filler cap is prop­
erly closed
c::> page 192.
In order to make an accurate diagnosis, the stor­
ed data can only be displayed using spec ia l diag­
nostic equipment (generic scan tool for 080).
In order to connect the specia l diagnostic equip ­
ment, push the plug into the Data Link Connector
(DLC). The DLC is located to the r ight of the hood
release
c::> fig. 16.
Your authorized Audi dealer or qualified work­
shop can interpret the code and perform the nec­
essary repair.
A WARNING
Do not use the diagnostic connector for per­
sonal use. Incorrect usage can cause malfunc­
tions, which can increase the risk of a colli­
sion!
Electronic speed limiter
Your vehicle may be factory equ ipped with tires
that are rated for a maximum speed of 130 mph
(210 km/h) . This is may be less than the maxi­
mum speed of your vehicle. To reduce the risk of
sudden tire failure and loss of control if the vehi ­
cle is operated at excessive speeds, your vehicle
has an e lectronic speed limiter. The electronic
speed limiter prevents your vehicle from going
faster than the tire speed rating. For more infor­
mation
c::> page 209.
-
If the engine contro l unit receives faulty vehicle
roadspeed signals, the Malfunction Indicator
Light (MIL)
II will illuminate. If this occurs, con­
tact the nearest author ized Audi dealer for assis­
tance.
A WARNING
Always observe the posted speed lim its and
adjust your speed to suit prevailing road, traf­
fic and weather conditions. Never drive your
vehicle faster than the maximum speed rating
of the tires installed.

Warm and cold
Warm and cold Climate control system
Description
The climate control system warms, cools and
adds humidity to the air in the vehicle interior. It
is the most effective when the windows and pow­
er top are closed.
If there is a build-up of heat in­
side the vehicle , ventilation can help to speed up
the cooling process.
In all heating mode functions except
defrost, the
blower only switches to a higher speed once the
engine coolant has reached a certain tempera­
ture.
Condensation from the cooling system can drip
and form a puddle of water under the vehicle.
This is normal and does not mean there is a leak.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.
The air pollutants filter must be changed at the
intervals specified in your Warranty & Mainte­
nance booklet, so that the air conditioner can
properly work.
If you drive your vehicle in an area with high air pollution , the filter may need to be changed
more frequently than specified in your Audi War­
ranty
& Maintenance booklet. If in doubt, ask
your authorized Audi Service Advisor for advice.
Key coded settings
The climate control settings are automatically
stored and assigned to the remote control key
that is in use . These settings are different when
the power top is open or closed.
_& WARNING
Reduced visibility is dangerous and can cause
accidents.
68
- For safe driving it is very important that all
windows be free of ice, snow and condensa­
tion.
- Completely familiarize yourself with the
proper use and function of the heating and
ventilation system and especially how to de­
fog and defrost the windows .
- Never use the windshield wiper/washer sys­
tem in freezing weather until you have
warmed the windshield first, using the heat­
ing and ventilation system . The washer solu­
tion may freeze on the windshield and re­
duce visibility .
(U;) Note
- If you suspect that the air conditioner has
been damaged, switch the system off to
avoid further damage and have it inspected
by a qualified dealership.
- Repairs to the Audi air conditioner require
special technical knowledge and special
tools. Contact an authorized Audi dealer for
assistance.
@ For the sake of the environment
By reducing the amount of fuel you use, you
also reduce the amount of pollutants emitted
into the air.
(D Tips
- Keep the air intake slots (in front of the
windshield) free from ice, snow and debris in order to maintain the proper function of
the climate control system.
- The energy management system may switch
the seat heating* or rear window defroster
off temporarily. These systems are available
again as soon as the energy balance has
been restored.
- Air escapes through vents under the rear
window. When placing items of clothing on
the luggage compartment cover, ensure
that the openings are not covered.

Fuel and R efue lin g
Gasoline additives
A major concern among many auto manufactur­
ers is carbon deposit build- up ca used by the type
of gasoline you use.
Although gasoline grades differ from one manu­
facturer to another, they have certa in things in
common. All gaso line grades contain substances
that can cause deposits to collect on v ita l engine
parts, such as fue l injectors and intake valves. Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP T IER Detergent Gas­
oline. For more information on TOP TIER Deter­
gent Gasoline, please go to the officia l website
(www.toptiergas.com).
After an extended period of using inadequate
fue ls, built-up carbon deposits can rob your en­
g ine of peak performance .
CD Note
-Damage or ma lf u nction due to poor fuel
quality is not covered by the Aud i New Vehi­
cle Limited Warranty .
- Do not add aftermarket f uel addit ive prod­
ucts to your fuel tank.
Refueling
Fuel filler neck
The fuel f iller neck is located on the r ight rear
side panel behind the fuel f iller flap .
If the power Locking system should fail, you can
still open the flap manually -for deta iled instruc­
tions seer:>
page 194.
You can find the fue l tank capacity of your vehicle
in r:>
page 246 .
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For more in­
formation about fue l specifications, see
c:> page 190 .
Your vehicle fuel tank has an on -board refuelling
vapor recovery system . This feature helps to pre­
vent fuel vapors from escaping from the tank and
192
po lluting the environment while you refuel your
vehicle. In order to fi ll the tank properly while
protecting the environment, please follow this
refueling procedure carefu lly.
A WARNING
Under normal operating conditions, never car­
ry additional fuel containers in your car. Gas
can isters and other containers used to trans­
port fuel can be dangerous. Such containers,
fu ll or empty, may leak and could ca use a fire
in a co llision.
If you must tra nsport f uel to
use for your lawn mower, snow blower, etc.,
be very careful and always observe local and
state laws regarding the use, transportation
and storage of such fue l containers . Make cer­
tain the container meets industry standards (ANSI/ASTM F852 -86).
CD Note
Never drive your vehicle until the fue l tank is
complete ly empty. The irregular supply of
f u el can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.

A WARNING
Improper refueling or handling of fue l can
cause fire, exp losion and severe burns.
-
- Fuel is highly flammable and can cause se­
vere burns and other injuries.
- Failure to shut the engine off whi le refuel­
ing and/or to insert the pump nozzle fu lly
into the fuel filler neck could cause fue l to
spray out of f iller neck or to overflow. Fuel
spray and overflow ing fuel can cause a fire.
- Never use a cellular telephone wh ile refuel­
ing. The electromagnetic radiation can
cause sparks that can ignite fuel vapors and
cause a fire.
- Never get back into your vehicle while refu­
eling. If in exceptional c ircumstances you
must get back in your vehicle while refuel­
ing, make certain that you close the door
and touch meta l to discharge static e lectric­
ity before touching the filler nozzle again.
Fu el and R efu elin g
Static electricity can cause sparks that can
ignite fue l vapors released during refue ling.
- Never smoke or have an open f lame any­
where in or near your vehicle when refueling or filling a portable fuel conta iner .
- For your safety, we strongly recommend
that you do not travel with a portable f uel
container in your veh icle. The container, full
or empty may leak and cou ld cause a fire,
especially in a crash .
- If, under exceptional c ircumstances, you
must transport a portab le fuel container,
please observe the following:
- Never fill a portable fuel container while it
is anywhere in or on the vehicle (for exam­
ple, in the l uggage compartment, or on
the trunk). Static e lectric ity can build up
while filling and can ignite fuel vapors
caus ing a fire .
-Always place a portab le fue l conta iner on
the ground before fill ing .
- Always keep the filler nozzle completely
inside the portable container before and
during f il li ng.
- If filling a portab le container made of
metal, the f iller nozzle must always be in
contact with the container. This will help prevent static electricity from d ischarging
and cause a fi re.
- Never spill fuel inside the vehicle or lug­
gage compartment. Fuel vapors are highly
flammable.
- Always observe local and state/provincial
laws regarding the use, storage and trans­
po rtation of fue l conta iners.
- Make certain the fuel conta iner meets in­
dustry standards (ANSI/ AS TM F852 -86).
(D Note
If any fuel has sp illed onto the car, it should
be removed immediately to prevent damage
to the pa int.
@) For the sake of the environment
As soon as the correct ly operated nozzle
switches off automat ically for the first time,

Fuel and Refueling
the tank is full. Do not try to add more fuel
because fuel may spill out. In addition, the
expansion space in the fuel tank will be filled -
causing the fuel to overflow when it becomes
warm and pollute the environment.
(D Tips
- Running your engine while refuelling may
cause vapors to escape or even cause fuel to
spill out of the tank. This would then shut
off the fuel nozzle before the tank is full.
- Do not refuel your vehicle with the ignition
turned on. The fuel gauge may otherwise
not indicate the correct fuel level after refu­
elling.
- The fuel filler flap of your vehicle is not
locked when you lock the vehicle from the
inside .
Unlocking the fuel filler flap by hand
You can open the fuel filler flap by hand if the
power locking system should fail.
